I have used Cabot's Timber oil (Mahogany) and I am not satisfied with it. It has essentially worn off in some areas and just looks tired in others. Can I go directly over it with Olympic Elite stain, or is some preparation work necessary? Thanks for your input.
You have to fully remove it first. Strip and brighten: https://www.deckstainhelp.com/restore-a-deck-injectable-deck-stain-stripper-review/
